(Hellmann) Koudegetallen sinds 1901 in De Bilt
Het koudegetal, ook wel aangeduid als het Hellmanngetal (H) naar de Duitse meteoroloog Gustav Hellmann, is een maat voor de koude in het tijdvak van 1 november van het voorafgaande jaar tot en met 31 maart van het genoemde jaar. Voorbeeld: 1963 heeft betrekking op de periode 1 november 1962 tot en met 31 maart 1963. Het wordt verkregen door over dit tijdvak alle etmaalgemiddelde temperaturen beneden het vriespunt te sommeren met weglating van het minteken.Actuele stand winter 2024/2025: 0.0 (t/m 10 december)
